A block of mass m = 2.00 kg is attached to a spring of force constant k = 565 N/m as shown in the figure below. The block is pulled to a position xi = 5.75 cm to the right of equilibrium and released from rest. (a) Find the speed the block has as it passes through equilibrium if the horizontal surface is frictionless. m/s (b) Find the speed the block has as it passes through equilibrium (for the first time) if the coefficient of friction between block and surface is μk = 0.350. m/s

Work. A block of mass m = 2.00 kg is attached to a spring of force constant k = 500 N/m as shown on the right. The block is pulled to a position xi = 5.00 cm to the right of equilibrium and released from rest. There is friction between the surface and the block. The coefficient of friction between block and surface is μk = 0.350. (a) (3 pts) What is the work done by the elastic force during the displacement? (b) (2 pts) What is the work done by the kinetic friction on the block during its motion? (2 pts) (d) (5 pts) What is the speed of the block as it passes through the equilibrium position? Use work-kinetic energy theorem.

A block of mass m1 = 16.0 kg is connected to a block of mass m2 = 32.0 kg by a massless string that passes over a light, frictionless pulley. The 32.0−kg block is connected to a spring that has negligible mass and a force constant of k = 300 N/m as shown in the figure below. The spring is unstretched when the system is as shown in the figure, and the incline is frictionless. The 16.0−kg block is pulled a distance h = 18.0 cm down the incline of angle θ = 40.0∘ and released from rest. Find the speed of each block when the spring is again unstretched. vm1 = m/s vm2 = m/s
